The rapid proliferation of tumor cells requires a large amount of nutrients, which requires the formation of new blood vessels in the tumor environment to meet this need. Humans discovered that tumor blood vessels expanded and grew rapidly in around a hundred years ago. Later, the dependence ... Views: 574
In light-sensitive higher organisms, the biological clock is a set of functional systems formed by photoreceptor neurons, endocrine systems, and gene timing oscillation expression regulation. It enables the organism to form a rhythm of day and night from microscopic levels of gene expression, ... Views: 610
Electric field therapy is a non-invasive method of tumor treatment that uses alternating electric fields of specific frequency and intensity to selectively destroy mitosis in cancer cells. Electric field therapy can target proteins that are critical to the cancer cell cycle, leading to mitotic ... Views: 622
Circulating tumor DNA (ctDNA) is a kind of free DNA released by tumor cells after necrosis and apoptosis. Because it circulates in the blood, the detection of ctDNA can reflect the tumor state in time. In 1940, Mandel and Métais first discovered the presence of free cellular nucleic acids in the ...

Mitochondria are a subcellular structure prevalent in eukaryotic cells and the most important source of energy in cells. Most tissue cells in the human body rely on oxidative phosphorylation of mitochondria to obtain the energy needed to maintain their metabolism. Mitochondria not only play an ... Views: 467
The hippocampus is one of the most studied parts of the brain (the cerebral cortex) in the central nervous system of mammals. Because the shape is similar to the hippocampus, it is called the hippocampus. In the human brain, the hippocampus is mainly responsible for learning and memory. The ... Views: 649
Dengue fever is a global acute infectious disease caused by dengue virus (DV). It is widely spread in tropical and subtropical regions. Its clinical manifestations include high fever, headache, muscle and joint pain, sometimes accompanied by rash, lymphadenopathy and leukopenia. Symptoms, when ... Views: 687
The CRISPR-Cas9 system has proven to be a powerful tool for genome editing, allowing for the precise modification of specific DNA sequences within a cell. Many efforts are currently underway to use the CRISPR-Cas9 system for the therapeutic correction of human genetic diseases. The best ... Views: 722
Fungus is the member in a big group which are made by eukaryotic organisms containing microorganisms. Most of them are not detrimental to human body, but some will lead to fungal disease. The reason is that biological compounds will be produced by fungi and some of compounds are harmful to ... Views: 640
